Transformation Procedure
Hello,
I am a Civil Designer (a non surveyor), trying to understand transformations. I am looking for confirmation that my below understanding of the procedure for transformation between datumA to datumB is a reasonable one, although conceptual.
Transformation of Vertical Datum (DatumA=>DatumB)
State Plane MapA (orthometric height)->GeoidA (orthometric height)->ellipsoidA (ellipsoid height)=> ellipsoidB (new ellipsoid height)-> GeoidB (orthometric height)-> State Plane MapB (orthometric height)
Transformation of Horizontal Datum (DatumA=>DatumB)
State Plane MapA (geodetic coordinate)->EllipsoidA (geodetic coordinate)=> EllipsoidB (geodetic coordinate)-> State Plane MapB (geodetic coordinate)
